Nice looking boomerang you have there Greg
the best thing will be having it look different to all the others out there.
I dont think your weight gain will be much and when I had my kit is was a little to light at 13.7lbs
the landings were so slow most guys were waiting for it to stall.
you will luv flying it and with the jet1A gear you can fly it off any field.
Job well Done
Pete
